Chelsea's Torres was sent off during Saturday's 1-1 draw with Tottenham, but neither of his two bookings was for laying his right hand on Vertonghen's face.
Television replays appeared to show Torres digging his nails into the Spurs defender's face, but the FA said it was powerless to sanction the striker as "one of the match officials saw the coming together of the two players, albeit not in its entirety."
That verdict has stunned Tottenham manager Villas-Boas, who said: "It's extremely difficult to know where to start.
"Obviously, it is almost a farcical decision. It doesn't matter to me which player or club is involved.
"Neither do I want to with my words put into question Fernando's integrity; neither their manager's, in trying to defend what is our position.
"I think the FA has made a decision almost a joke. It looks incredible. How can you see the images, pretty clear, and come out without punishment, on something which overtakes all professional behaviour?
"I think the decision is a disgrace. If the committee can't solve such clear images I don't think it sets out a good first example.
"I think the FA has lost all opportunity to put some sense into the images everybody saw."
Jose Mourinho comments are even more disgraceful than the FA here. Fernando "the bitch" Torres cheated throughout the match with his diving, scratching, kicking and flying elbow into Vertongen, the victim in all this. The Portuguese coward who has no integrity whatsoever then attacks the victim????? Torres should have received a 4 match ban for scratching another man's face alone.- soul controller
